The maximum output power of the TNY266G-TL depends on the input voltage, output voltage, and the transformer turns ratio. However, as a general guideline, it can deliver up to 6.5 W of output power with a 230 VAC input and a 5 V output.
The transformer selection depends on the input voltage, output voltage, and output power. Power Integrations provides a transformer selection guide in the datasheet, which can be used to select the right transformer. Additionally, the company also provides a transformer design tool on their website.
The BYPASS pin is used to bypass the internal voltage regulator and connect an external voltage source to power the IC. This pin can be used to improve the efficiency of the converter by using a more efficient voltage regulator or to power the IC from a different voltage source.
To ensure that the TNY266G-TL operates within the SOA, the designer should ensure that the input voltage, output voltage, and output current are within the recommended limits. Additionally, the designer should also ensure that the IC is properly cooled and that the thermal design is adequate to prevent overheating.
The CS pin is the current sense pin, which is used to sense the output current of the converter. The voltage on this pin is proportional to the output current, and it can be used to implement overcurrent protection and current limiting.
